How to change water and exhaust the v8 water tank of Elysee?

The method of replacing the water in the water tank and discharging it is as follows: (1) After the automobile engine is cooled, unscrew the water tank cover, open the water drain valve of the water tank (at the bottom of the water tank) and discharge the antifreeze. (2) Insert the rubber hose connected with the tap water pipe into the water inlet of the water tank, turn on the tap water tap, and let the tap water continuously flow through the engine cooling system. During the flushing operation, let the engine run at idle speed and keep the above operation until the water tank releases clear water. (3) Turn off the tap water, and then turn off the drain valve of the water tank after the water in the cooling system is exhausted. (4) Add antifreeze from the water inlet of the water tank, and fill the water tank with antifreeze. Unscrew the cover of the liquid storage tank, add antifreeze, and reach the "Max" scale line, and be careful not to exceed the "Max" scale line. (5) Cover the water tank cover and the liquid storage tank cover and tighten them. (6) Start the engine, idle for 2 ~ 3 minutes, and unscrew the water tank cover. At this time, because some air is excluded from the cooling system, the liquid level of antifreeze will decrease. At this time, antifreeze should be supplemented to make antifreeze reach the "Max" scale. (7) Cover the water tank cover.
